The third soldier to be court-martialed in hazing related to the Oct. 3 suicide of Army Pvt. Danny Chen in Afghanistan was found guilty of dereliction of duty Friday after pleading guilty to wrongfully possessing and consuming alcohol in violation of a general order.

Staff Sgt. Blaine Dugas, an infantryman assigned to the 1st Brigade Combat Team, 25th Infantry Division at Fort Wainwright, was demoted to sergeant and sentenced to three months of confinement with a 90-day credit for time served before his trial.

The charges relate to Dugas’ failure to prevent subordinates from mistreating Chen, 19, and engaging in abusive behavior, as well as a false statement Dugas made to investigators claiming he hadn’t been informed of Chen’s mistreatment.

In previous courts-martial related to the Chen case, Sgt. Adam Holcomb was sentenced last month to 30 days in prison and a demotion, while Spc. Ryan J. Offutt received a six-month sentence earlier this week as well as a demotion to private and a bad conduct discharge.
